WINDING-MACHINE.

Specification of Letters Patent. Patented line 11, 1918.

Application filed January 6, 1917. Serial No. 141,019.

To all whom it may concern:

Be it known that I, MARK B. WHITE, a citizen of the United States, and a resident of Hanover, in the county of J o Daviess and State of Illinois, have invented a certain new and useful Improvement in VVinding- Machines, of which the following is a description, reference being had to the accompanying drawings, which form a partof my specification. l

The invention contemplates mechanism whereby the twisted yarn or thread is imme diately wound on bobbins operated so as to maintain the proper twist of the yarn as it is discharged by or passes from the twisting head or mechanism, with the result that a finished yarn is provided, ready for use on the looms and in the warping department.

A further object of my invention is to provide a construction which will enable more finished yarn or thread to be placed on the bobbins.

The invention will be more fully comprehended from the following detailed description of the accompanying drawings, Where- 111:-

Figure l is a side elevation of a single unit of a composite machine or battery comprising the roving-receiving and tension-applying mechanism, the spinning mechanism and the winding mechanism.

Fig. 2 is a detail view of the roving-receiving and tension-applying rolls, taken on the line 22 ofFig. 1, illustrating their arrangement for a battery or plurality of units.

Fig. 3 is a plan view of i the winding mechanism.

Fig. at is a central longitudinal sectional view of Fig. 3.

Fig. 5 is a detail view of the yarn-controlling device of the Winding mechanism, taken on the line 1111 of Fig. 3, looking in the direction of the arrows.

F 6 is an enlarged detail view in side elevation, of the construction shown in Fig. 5. I

Fig. 7 is a cross sectional view, taken on the line 13-13 of Fig. 3, looking in the direction of the arrow Fig. 8 is a cross sectional view, taken on the line 1- -14E of Fig 3, looking in the direction of the arrows.

In the particular exemplification of the invention. as illustrated in the drawings, a single unit is merely illustrated and only portions of a suitable supporting frame shown; it being understood, of course, that these machines are usually composed of a number of units constituting what may be termed a battery; all of the units being preferably driven from a common drive shaft provided with graduated or stepped pulleys in order to permit the speed of the various units to be varied commensurate with the speed of delivery from the carding ma- 0 lines. As the method of driving the various units of a battery from a common driver or shaft maybe the same as the method at present employed, this part of the mechanism has not been elaborately illustrated and need not therefore be minutely described. For the purpose of the present specification, we will assume that my improved machine is to be employed in producing woolen yarn made from the roving as it is discharged from the carding machine. Theroving is indicated at 20 inFig. 1, and is fed between the tension-applying rollers indicated at 21, 22 and 23. As the roving is to be fed directly to the twisting mechanism of my machine, the tension-applying rollers must, therefore, be operated at substantially the same speed the speed of delivery of the carding machine, and for that reason the pulley 24 receives a belt 25, driven 0E of a suitable drive-shaft or pulley on the carding machine. The pulley 24: is mounted on shaft 26 having suitable bearings in the brackets 27; the shaft being provided with a pinion 28 adapted to mesh with gears 29 and 30 of rollers 21 and 22, respectively, so that positive rotation will be imparted to the rollers 21 and 22 in similar directions. The

brackets 27 extend into horizontal planes above the rollers 21 and 22, at opposite sides of the machine and provide suitable bearings for the ends of the end rollers 23; the latter being disposed in a vertical plane intermediate of the vertical planes of the axes of rollers 21 and 22. The roller 23 is loosely mounted so as to rest on the rollers 21 and 22 and be rotated thereby. In a composite machine or battery, consisting of a number of units, a separate loosely mounted roller 23 is provided for each unit as disclosed in Fig. 2; the abutting ends of the different rollers being preferably provided with a slight conical surface, as shown in Fig. 2, so as to obviate a too great frictional relation between the adjacent ends and at the same time maintain the rollers in proper relation and therefore in alinement with. the discharge portions of the rub rolls or apron of the carding machine. The rollers 23 ride loosely on the lower rolls 21 and 22 and are of weight sufficient to apply the necessary tension or draft on the roving or sliver in the passage thereof to the twisting mechanism, a description of which mechanism will not further be entered into in this specification.

The roving or sliver, indicated at 4L1, passes from the tension-applying rollers 21, 23 and 24 directly into the twisting head indicated at 31 and the twisted yarn, indicated at 41'' resulting from the operation of the twisting head, passes from the discharge end of said head 31 and is then fed to the winding mechanism at the left-hand end of the construction as illustrated in Fig. 1. This winding mechanism consists of a 1'0- tating bobbin-carrying frame rotatirely mounted in suitable brackets or standards 63, 63; the frame comprising end meml'iers or plates (E i and 65 which are provided with hubs or projections 66 and 67 adapted to be mounted in suitable bushings in the standards or brackets 63; the hub 66 being provided with a pulley 68 which receives the driving belt or member 69 driven by means of suitable stepped pulley indicated at 70 in Fig. 1; the latter being mounted on a cross shaft and may be rotated by means of the belt 71 which, in turn, may be driven off of suitable pulleys mounted on the shaft (31. The pulleys 70 are preferably graduated and made to correspond with the pulleys 60 which receive the belt 59 of "the twisting head, so that the bobbin-carrying frame may be driven at substantially the same speed as the twisting head and also driven in the same direction as said head in order to maintain the twist in the yarn given thereto by the twisting mechanism.

The end members or arms 64 and 65 are maintained in proper relation with each other by the longitudinal rods 7 2 which extend through suitable openings in the end members or arms and are clamped in place by means of nuts 7 3, see Fig. 4-.

One end of each end member or transversely disposed arm is enlarged or flared, as more clearly shown in Figs. 7 and 8, so as to provide sufficient space, for one or more holding rods 72 as well as two screwrods 74 and 75; the sustaining rod 72, on this side of the frame, being preferably located intermediate of the screw-rods 7a and 7 5, see Figs. 3, 7 and 8. One of the screwrods is provided with a right-hand thread, while the other screw-rod is provided with a left-hand thread, so that the mechanisnn later to be described and controlled by said rods, will be caused to move in opposite directions. The hub or extension 66 is provided with .an opening preferably in the mounted on. a spindle 78, one end whereof is seated in a suitable opening or ferrule 79 formed or secured centrally in the hubportion of end member or arm (i l at a point concentric with the axis of the carrying frame and the bobbin. The opposite end of 5 the spindle 7 S is hingedly secured at 80 to an extension or trunnion 81 which is adapted to pass through the hub 67. The hub 67 is preferably shown counter-bored to receive the end of a coil spring S2 which encircles the extension or trunnion S1 and bears against the end portion or head 83 formed on the inner end of extension 81 to provide the pivotal point 80; the spring 82 tending to press the spindle with the bobbin toward the right in Figs. 3 and l and thus maintain the opposite .end of the spindle 78 in the opening or ferrule 79 at the yarn-receiving end of the winding frame.

The extension 81 of the spindle passes through the hub 67 to the outside thereof to receive a pulley 84:, preferably loosely mounted thereon. The pulley 8% receives a belt 85 which extends about a pulley 86 mounted in the lower part of the frame of the machine; the last-mentioned pulley being driven by means of a belt 87, which may, in turn, be driven from proper pulleys mounted on the same shaft as pulley 70. The belts 69 and 85 are arranged to rotate both the carrying frame and the bobbinspindle in similar directions; the bobbinspindle, in practice, is rotated at a faster speed than the carrying frame. in order to wind the yarn on the bobbin.

Slidably mounted on the two connecting or tie rods 72 arranged on the same longitudinal side of the carrying frame, is riding threader or guide comprising the block or member 88; the upper side whereof is provided with an extension or lug adapted to provide a pivotal point at 89 for a straddling member or yoke 90. The member or yoke 90 is provided with an opening for the passage of a screw-rod 91 mounted in the block 88 adjacent one end thereof. The screw-rod or stem 91 is encircled by a suitable coil-spring 92; one end whereof bears down on the block 88 while the other end bears upward against the member 91. The end of the rod or stem 91 above the member 90 is provided with a thumb nut 93 whereby the extent or degree of action of spring 92 on member 90 is controlled. The member or yoke 90 is provided with a plate or shoe 94 arranged between the two sides or legs'of member '90 and pivotally secured to themember 90 at the point 95, see Figs.

" and 6,'by means of suitable lugs or ears pro- 'vided on the plate 94. The plate or shoe 94' is preferably bent downwardly toward the bobbin-77, andits forwardlypresented end I provided with the opposing lugs or book relation with the bobbin.

bar or pm 102. Asis more clearly evident from Fig. 6, the pivotal points 89, 95 and :portions 96, 96, on the upper surface, as "shown in Fig. 5. 1 These hook-portions are adapted to guide the spun yarn 41* which comes from the discharge end of the spinning mechanism and is passed through the slot 76' of theendmember 64 and led lengthwise of the Winding-frame; the yarn being then passed beneaththe rearward extending portion 97 of the shoe and through the opening 98 of the shoe so as to come across the top of the forwardly presented portion and in engagement with'one of thehook-por- 'tion's 96; theyarn in Fig. 5 being shown in engagement with thehook portion 96 to the rightofthe shoe because the bobbin ,77is assumed to be rotating inclockwise direction.

shoe (therefore to one side of the pivotal point 95), while the other end of the spring will be to draw the rear end of theshoe upward and therefore depress the forward end, provided with the hooks 96,iinto close Pivotally mounted in the block or member 88, at a point abovethepivotal point 95 of the shoe,are a pair of screw-rod engaging members or arms 100 and 101; the'member 100 being presented forwardly in the same direction as the hook or forwardend of shoe 94, while the other memberlOl is presented rearwardly, namely toward the end of the winding frame" at which the yarn 4l enters the'same. Bothmembers-100*and 101 are mounted ona mduoa, which is rotatably mountedin theblock88. One endofthe rod 102 is made crank-shape and has, the end of a spring 103 secured thereto, while the other end of the springissecuredto the pivotproviding member 89, which is extended out beyond the side ofthe guiding mechanism'so as to permit thespring'103 to exerta direct upward pull on the-crankarm portion of the 102. are all arranged substantially in the same vertical plane, so that the tendencyof spring 103 will be to pull the crank arm 102 to either side of itspivotal or fulcrum point upon the slightest pressure being exerted against the crank arm when the latter has been moved so that spring 103 is pulling againstthedead center of the pm or arm '103. The rearward extension 97 of the shoe :94 is providedwith a pair oflugs 104 and r 105' arranged at predetermined distances apart, see Fig. 6, and adapted to receivethe crank arm 102 therebetween, as shown in,

Figs. 5 and 6. Asis evident from this construction, if the hook end or forward portion of shoe94, in Fig. 6, is elevated by the increasing quantity of yarn on the bobbin, the lug 105 onthe rear extension 97 of shoe 94 will be brought into striking engagement with the crank arm 102 and cause the crank armto be swung toward the left in Fig. 6; and through the action of its spring 103 be moved toward the opposite side of the pivotal point 95 and therefore into close relation with the lug 104. 1

-The ends of the screw-rods 74 and 75 are extended slightlythrough the endplate of the frame and are each provided with pinions 106 and l07,respectively; the'pinions106 and 107 beingsuitablysecuredto the ends of the screw-rods'74 and 75, re spectively, so as to rotate therewith. The

hub 67 of the frame has bearing in a pinion 108, see Fig. 4, which in turn is secured in the frame 63 and held against rotation.

This pinion 108 meshes with both pinions 106 and 107 so that rotation of the frame,

by means of the, belt 69, which takes about 68 at the opposite end of the frame, will cause the pinions 106 and 107 to move through an orbit about stationary pinion 108 which causes pinions 106 and 107 to rotate and impart rotation to their respective screw-rods 74 and 75. r

The free or outer ends of member or arms 100 and 101 are provided with threaded or serrated surfaces correlated to the threads on the respective screw-rod with which each arm is intended to contact; so that the threads of the rods, when the latter are rotated, will induce the Windingmechanism to slide or be'moved on therods 72 in the direction of the lead ofthe threads of the screw-rod WlllOlI is in operative relation with its respective arm. a

The yarn is started on the bobbin 77 at the base of the'cone portion 77*; the composite guide mechanism being moved along the rods 72 into proximity with the base .of the cone portion. This necessitates'the forward or hook end of the shoe 94 to be elevated at and consequently force the rearward extension 97 downwardly, which causes the lug 105 to come into engagement with the crank-arm 102 and force the "latter to a point where it will be tripped through the action of its spring 103 and thereby induce armor member 100to be moved into operative engagement with its correlated screw-rod; the lead of whose threads are such that, the rotation of said rod (induced by the intermeshing pinions heretofore described), cause the compo'site? guide mechanism I to be, moved along Ethe rods f72 toward the opposite end of the bobbin; This-movement of :the 1 composite guide -mechahism continues {for "a short zperiod until the for'ward or hook-end of the shoe 94: has reachedthe limit of its low- -ermost-position (the forward endofthe shoe being forced downward throughthe action of its spring 99). at which timethe 113% 104twill'have moved the crank-arm 102 's ciently to the rightvin Fig. 6 so that the "springil03- will cause the crank arm to :swing" into the position shown in Fig. 6, infill 1G1) toward the right of the pivotal point "95; such, movement of the crank arm will force arm ormember 100 out ofoperative engagement with its correlatedscrew-rojd and cause member or arm 101 to be thrown il'itoroperative engagementwith its correlated screw-rod, the lead of whose threads is in the opposite direction. Thiswill cause the 'composite rguide mechani'sm, ,through rotation of the screw-rod, to r travel F in @the" reverse direction along the rods 72, 'untilflthe -for- :wardor hool'eend of shoe 94: reaches the limit .of its highest or elevated position, namely the position where ring 105 will causethecrankarm 102 to be trippedinfthe opposite? direction, .as previously described. As is evident "from :the construction shown and "the foregoing description, the maximum high and maximum low points for? the forward endof the shoe will constantly be advancing relativewto the base portion o the bobbin as the amount of yarn on the bobbin increases, until the opposite or small end of the bobbin has beenreached, at which time'the bobbin will have beenyfilled with thespun yarn woundin overlapping stages. The forward endof the shoeis slightly curved upwardly so as; to permit the latter to slide freely across the :wound yarn dur- "ing its backward and :forward travel in short stagesfrom one endnof the bobbin to thelothen- The forward, end of the shoe is :providedwith the two hool -portio11s so that yarnmay be woundrin either direction on It is apparent that the'speed of the bobbin will haveto ary'andbe commensurate with": the diameter of the portion at which vthe yarn is being wound; in i order to-i-take up theyarn' as' it: is fed: to theYwmdmg -mecha1iism.
